Simple Simon, despite its deceptively simple name, is a surprisingly challenging solitaire game.
The objective is to transfer all cards to the four foundation piles, arranging them by suit from Ace to King.
A card can be placed on another card only if its rank is one higher. Multiple cards can be moved as a unit if they form a consecutive sequence of the same suit.
Empty spaces (free cells) can be filled with any card.
Victory is achieved when all cards have been successfully moved to the foundations.
